Section 7: Reading Buffers
Series 2600A System SourceMeter® Instruments Reference Manual
Reading buffer overview
Reading buffers capture measurements, ranges, the instrument status, and the output state of the
Keithley Instruments Series 2600A SourceMeter
®
instrument. The Series 2600A has two
dedicated reading buffers per channel. You can use the dedicated reading buffers to acquire
readings or you can use the ICL command to create dynamic reading buffers.
Each dedicated reading buffer in the Series 2600A can store over 60,000 readings with the time
stamps and source values options enabled. Disable the time stamps and source values options to
store over 140,000 readings internally.
You can save the dedicated reading buffers to internal nonvolatile memory in the instrument or to
the USB flash drive.
Once you save the reading buffers to the USB flash drive, insert the USB flash drive into the USB
port on your PC to view the data in any compatible data analysis application or transfer the data
from the USB flash drive to your PC.
NOTE Reading buffers other than the dedicated reading buffers have fixed
capacity and are not specifically limited to 60,000 or 140,000.
Working with reading buffers in the local state
Use this section to store and recall reading buffers while in local mode operation.
